<p>Is there a page where I can see recent results for <code>cargo build -Ztimings</code> for bootstrapping? Thanks!</p>

<p>Yeah, it would be nice to see up-to-date <code>-Z timings</code>, but that at least has some of the information</p>

<p>Seems like <code>rustc_mir</code> might also be a candidate for splitting up</p>

<p>Though it has many fewer dependents IIUC</p>

<p>Seems like <code>rustc_middle</code> has roughly 60 direct and transitive dependents, while <code>rustc_mir</code> has only 4</p>

<p>Only the driver/rustc_interface depend on <code>rustc_mir</code></p>
